Using Labeled and Unlabeled Tapes
Using the NOUNLOAD Option
The NOUNLOAD option directs the BACKUP utility to rewind the final tape and
leave it online in the drive when the BACKUP process is completed. If the
NOUNLOAD option in the BACKUP command is not specified, the robot returns
the last cartridge tape to its slot within the tape library when the drive is finished
writing to the tape. The robot then loads the next cartridge requested.

Using Labeled and Unlabeled Tapes
NonStop systems support two standard tape-label formats:
•
ANSI
•
IBM-MVS
Using the MEDIACOM Utility for Labeled-Tape Operation
MEDIACOM is the utility for managing labeled-tape operations. MEDIACOM
replaces TAPECOM and provides the operator interface to the Distribute
Systems Management (DSM)/Tape Catalog.
Use MEDIACOM commands to:
•
Label new tapes and catalog them
•
Handle tape mount requests
•
Manage the use of uncataloged tapes
•
Create scratch tapes
Note. Because they can be cataloged and offer security features for protecting data, you
should use labeled tapes with the 9840 tape drive.
